yeah it totally depends on the translators, some will stop and others will continue translating (How to Get My Husband on My Side, The Count’s Secret Maid…) especially japanese mangas
the official tl is often behind because they start translating after the raws gained popularity and the schedule is one chapter per week so they can't catch up
but recently there are global releases when raws and official tl are uploaded the same day, for exemple Our sunny days, Blossoms of the white night, The hounds of sisyphus…

Okay it's going to be many questions and long ones but I hope someone understands what I want to ask and awnser me
Do the group/person who is translating a specific manhwa stops the moment there is an official translation? Cuz many manhwa I realized the group/person stops the moment there is a official translation, or is it depends on the group/person?
Also is the official translation is slow or is it just cuz it would take time to reach where the group/person has left? Like do they upload a weekly chapters? Just a few chapters behind the korean ones?
I don't know how to ask it or say it but what I really want to know it the official translation slow?or just cuz they are behind the main chapters and they just need to times to reach where the group/person have stopped?
Hope someone understands me and awnser me
